Teignmouth, England, United Kingdom presents a moderately challenging location for year-round solar PV energy generation, with significant seasonal variations typical of its Northern Temperate Zone position.

Seasonal Solar Performance

The solar energy output at this location shows dramatic seasonal swings. Summer delivers the strongest performance at 5.80kWh per day per kW of installed capacity, making it an excellent time for solar generation. Spring follows as the second-best season with 4.86kWh per day per kW, offering nearly comparable output to summer months. Autumn sees a notable decline to 2.45kWh per day per kW, while winter presents the most challenging conditions with only 1.07kWh per day per kW. This represents more than a five-fold difference between peak summer and winter production, highlighting the location's strong seasonal dependency. For optimal year-round performance, solar panels should be installed at a fixed tilt angle of 43 degrees facing south. This angle maximizes total annual energy production by balancing the sun's varying elevation throughout the year.

Local Factors Affecting Solar Production

Several environmental and weather factors in Teignmouth can significantly impact solar panel performance:

• Salt air corrosion from coastal proximity
• Frequent cloud cover and overcast skies typical of the UK climate
• High humidity and moisture levels
• Strong coastal winds carrying salt spray
• Regular rainfall throughout the year

Preventative Measures for Better Performance

To combat these local challenges, several installation strategies can help maintain optimal energy production. Choose marine-grade mounting hardware and corrosion-resistant materials specifically designed for coastal environments. Regular cleaning schedules become essential to remove salt deposits and debris that accumulate on panel surfaces. Install panels with adequate ventilation spacing to prevent moisture buildup and allow proper airflow. Consider anti-reflective coatings that perform better in diffuse light conditions common during overcast weather. Secure mounting systems must withstand strong coastal winds while maintaining proper panel orientation. Professional maintenance contracts prove valuable in coastal locations, ensuring regular inspection and cleaning that individual homeowners might overlook. Proper drainage systems around installations prevent water pooling that could damage electrical components over time.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Teignmouth

Seasonal solar PV output for Latitude: 50.5455, Longitude: -3.4911 (Teignmouth, United Kingdom), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 43° South in Teignmouth, United Kingdom

To maximize your solar PV system's energy output in Teignmouth, United Kingdom (Lat/Long 50.5455, -3.4911) throughout the year, you should tilt your panels at an angle of 43° South for fixed panel installations.

As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.

We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Teignmouth, United Kingdom

If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Teignmouth, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
34° South in Summer	54° South in Autumn	64° South in Winter	42° South in Spring

Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.

This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Calculate solar panel row spacing in Teignmouth, United Kingdom

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Teignmouth, United Kingdom.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. Minimum Spacing:
   We add the shadow length to the horizontal space occupied by tilted panels.

This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.

Topography for solar PV around Teignmouth, United Kingdom

Topographical Features Around Teignmouth

Teignmouth sits at the mouth of the River Teign on the south Devon coast, where the river meets the English Channel. The immediate area around the town is characterized by relatively flat coastal terrain, with the settlement built on low-lying ground that gradually rises inland. The Teign estuary creates a natural break in the coastline, with mudflats and marshland extending upstream from the town center.

Moving inland from Teignmouth, the landscape begins to climb steadily into the foothills of Dartmoor National Park. The terrain becomes increasingly undulating as it approaches the moor's edge, with rolling hills and valleys carved by numerous small streams and tributaries of the River Teign. These hills typically range from gentle slopes to more pronounced inclines, creating a varied topographical pattern across the region.

To the north and northwest of Teignmouth, the land rises more dramatically toward the granite uplands of Dartmoor. This ancient landscape features exposed tors, deep valleys known as cleaves, and expansive moorland plateaus. The transition from coastal plain to moorland creates a distinctive stepped appearance in the terrain, with each elevation band offering different microclimates and land use patterns.

Optimal Areas for Large-Scale Solar Development

The most promising locations for substantial solar photovoltaic installations lie in the gently undulating agricultural land between Teignmouth and the steeper Dartmoor slopes. This intermediate zone offers several advantages, including relatively stable ground conditions, moderate slopes that can be engineered for optimal panel orientation, and existing agricultural land that could potentially be converted or used for agrivoltaic applications.

The coastal plain immediately around Teignmouth, while topographically suitable, presents challenges due to existing urban development and the high value placed on coastal land for residential and commercial uses. However, some industrial areas and brownfield sites within this zone could offer opportunities for solar development without competing with prime agricultural or residential land.

Areas to the east and west along the coast, particularly around Newton Abbot and toward Dawlish, feature expansive relatively flat agricultural fields that would be well-suited to large solar arrays. These locations benefit from stable geology, good transport links for construction and maintenance, and proximity to existing electrical infrastructure.

The higher elevations approaching Dartmoor, while offering excellent exposure, present practical challenges including steeper gradients, more challenging ground conditions, protected landscape designations, and increased exposure to weather extremes. These factors generally make such areas less economically viable for large-scale solar development, despite their elevated positions and reduced shading from surrounding features.
